Countries are preparing to manage 140 people on a hantavirus-stricken cruise ship headed for the Canary Islands. The ship is expected to reach Tenerife early Sunday morning. Hantavirus is usually spread by inhaling contaminated rodent droppings and isn’t easily transmitted between people. The World Health Organization says the risk to the public is low. At least three passengers have died, and several others are sick. Spanish authorities are preparing to receive the passengers and crew. It’s unclear if they will be quarantined. The United States and Britain plan to repatriate their citizens.
